Check Your Options
Some iPhone 7 shipping dates have already been pushed into November. If you failed to get the device you wanted, you'll want to check around before putting in an order.
Some devices (Jet Black iPhone 7 and others) are now impossible to get by September 16th. As we push away from the release date, shipping dates are going to continue to fluctutate for better or worse. This is why you'll want to check your options across various retailers.
Check Apple, carrier sites and retailers to see how you can get the model you want the fastest. Shipping estimates will differ so you don't want to limit your options.
Keep an eye out as we approach the iPhone 7 release date.
